VALVE AND OPERATING MECHANISM THEREFOR.

' Specification of Letters Patent. Patented July 18:, 1911:

Application filed September 6, 1910. Serial No. 580,585.

from a supply thereof; other objects are tocombine in a single valve-construction a petcock and:fluid supply-controlling valve for an internal-combustion engine; to provide a valve for supplying oil to an'engine of-the type referred to of such a construction as will prevent the blowing of the fluid out of the valve when the engine contains a compressed-charge; and to provideforthe simultaneous operation of a plurality of fluidcontrolling valves of a multiple-cylinder internal-combustion engine.

The priming valves forinternal-combus tionengines as hitherto constructed are so formed as toafiord direct and open'communication of the oil-reservoir or conduit to the cylinderof the-engine when the valve is opened, and thus liability of causing an excess of oil to flow into the cylinder and furthermore be blown from the valve, should the cylinder contain compressed gases when the valve is opened, is presented, the overcoming of the objections just stated being one of the objects of my invention.

. I have devised my invention for use, more particularly, in connection with an internalcombustion engine, and especially for controlling the introduction of fuel-oil, such as lar valve-devices illustrated as connected with the cylinders shown .in Fig. 1, show-' jmosphere, namely while operating as a petcock. Fig. 3 is a view in end elevation of the valve illustrated in Fig. 2 showing diagrammatically two positions assumed by the operating lever of the valveduring the operation thereof. Fig. 1 is a. section taken .on thelin'e 4* in Fig. 2 and viewed in the direction of the arrow. Fig. 5 is a section taken at the line 5 on Fig. 2 and viewed in tlie direction of the arrow. Figs. 6 and 7 are views like Figs. 4c and 5, showing the position assumed 'by the valve-plug when the Q operating lever therefor is turned to the posltion represented by the dotted line in Fig. 3. Figs. 8 and 9 are views like Figs. 4 and Y 5 respectively, showing the position the i valve-plug assumes when its operating lever fis turned to the position represented by-the iClOt-iLHCl-ditSll line of Fig. 8. Fig. 10 is a view in side elevation of the valve-plug; and Fig. 11, a view in elevation, partly sectional, of the valve of Fig. 2shown as equipped with i'an oil-reservoir.

I The front reach of the chassis of an automobile is represented at 15 and is shown as supporting a t c-cylinder internal-combustion 'engine 16 of well-known type, the 'hood for the same being represented at 17 and the dash-board of the car at 18.

Each of the cylinders represented at 19 is 'shown as equipped with a combined pet-' cockand priming valve 20 embodying my invention, a description of the valve-construction being as follows: The casing of ithe valve which is represented at 21 and'isformed with a conical bore 22, is provided with a depending extension 23, which it is Fig. 2. Adjacent to the larger end of the I casing 21 is a tubular extens on 25 conta'ining a conduit 26 which opensinto the bore 22 as represented in Fig.2, this conduit beingadaptedto be connected with. an oilsupply as through a pipe 27.

.valve-plu 28 which is held' in contact with theconica walls of the bore by a spring 29. iThef plugf28 is provided witha port 30,.

Rotatably confined 1n the bore 22 is a -eqi111ipped with the valve, to the atmosphere.

e plug 28 contains a chamber 31 having inlet and outlet ports 32 and 33 respectively,

the outlet port 33 opening into a channel 34 formed in the outer surface of the plug and so disposed that when the plug is turned to a lcertamposition as hereinafter described, the channel 34 will be open to the lower section of the conduit 24.

Thefluid to be controlled by the valve en-j 't'ers the chamber 31 throughthe inlet 32and discharges from this chamber through the channel 34 into the conduit'24 and then into the cylinder of the engine, the positions of the inlet and outlet 32 and 33, respectively,

being such, as illustrated, as to cause the chamber 31 to fill with oil from the conduit;

26 when the plug 28 is in one position and be closed to the conduit 24; and closed to v the conduit 26 and open to the conduit 24 '25 when the plug is in another position, and

the outlet 33 so disposed as .to be closedto I the conduit 24 when the port 30 registers with the latter.

' As a convenient means of operating the plug 28 of the valve, I employ a lever which, when turned to the trated in Figs. '1 and 2, so positions the plug .as, to cause the port130 to register with the conduit 24 and close both the inlet and outlet 32 and 33,,respectively, of the chamber '31. When-the lever is moved to the right in Fig. 3 to the position indicated by the I dotted line, which would be the normal position of the; valve-plug in use, it will turn the latter to the position illustrated in Figs. 6 and 7', in which theport 30 is out of registration with the conduit 24, and the cham- .ber 31 communicates with the conduit 26.

When the lever 35 is moved to the position indicated by the dot-and-dash line in Fig. 3

the port 30 and the inlet 26 will be out of registration with the conduit 24- and the chamber 31 respectively, but the channel 34 will communicate with the conduit 24, thus permitting the fluid preparatorily admitted to the chamber3l to flow therefrom into the cylinder. Thus when the valve is operating as a pet-cock, the flow of oil from the valve is prevented, and while the valve is operating to discharge fluid therefrom the petcock is closed.

In Fig. 1 the conduits 27 are illustrated as connected with a pipe 36 which, connects with a fuel-oil supply-tank 37 located at any convenient point on the car, from which the pipe 36 and conduits 27 are maintained full of oil; and the lever 35 of each valve 20 is shown as pivotally connected with a longitudinally shiftable bar 38 which is pivoted to the upwardly-extending arm 39 osition illusof a bell-crank 4O fulcrumed, as indicated at 41, on the car at any suitable point accessible which its arm 42 is opposite the arrow on the dial 44, the plugs 28 of the valves occupy the positions illustrated in'Figs. 6 and 7 in which the chambers 31 thereof fill with oil; and when the lever 40 is swung to a posi-. tion in which its arm 42 strikes a stop 45 on the plate 44, the plugs 28 are positioned for discharging the fluid from the chambers 31 into the cylinders 19. Thus the operator may with ease prime the cylinders of the engine without removing the hood from the engine.

It will be understood that the valves 20 need not be connected together for simultaneous operation, nor need each cylinder 19 be equipped with a valve, nor the valves 20 be connected with a pipe 36 common to all of the valves, in carrying out my invention.

.Furthermore, the oil-supply may take the form of a receptacle connected with the conduit 26 and each valve carry such a receptacle, as illustrated in Fig. 11, wherein the receptacle is represented 3.1)426, the receptacle preferably'being of a size suflicient to hold fluid for a number of charges to the cylinder with which it is equipped.

It will be manifest that my invention need not be, as to certain features thereof, embodied in a combined pet-cock and fuel-oilcontrolling valve, as it may be utilized to great advantage for furnishing lubricating oil to surfaces to be lubricated. Furthermore, the fluid-controlling feature of the valve is hi hly useful Without the pet-cock feature an er some conditions, for regulating the flow of either fuel-oil or lubricating oil, as by its incorporation in a valve-device a predetermined amount of oil only can be dischargedfrom the supply at any one time, this being of special importance in the priming of an engine, as an excess of oil retards the operation thereof.

A valve constructed in accordance with my invention affords a further advantage in that the supply of fluid is shut off from the cylinder of the engine when the latter is receiving a charge from the valve, and thus if the cylinder happens to contain gas under compression, .the fluid dischargedfrom the valve cannot be blown back into the conduit or tank from which it was drawn.

What I'claim as new, and desire to secure by Letters Patent, is

In a combined pet-cock and oil-supply-- conducting port angularly disposed with reing device, a valve common to both the petcock' and said device'and containing a petcock and an oil-conducting port angularly disposed with relation to each other, wherebysaid valve is adapted to simultaneously open the pet-cock port and close the oilconducting port, or to close the pet-cock port and to open the oil-conducting port..
